Elements, Compounds, and Mixtures Element
Compound
An element is a 100% pure substance that can NOT be broken down. It consists of only ONE type of atom. For example, gold has ______ atoms.
A chemical compound consists of DIFFERENT elements that are chemically combined from a chemical reaction. Compounds can only be taken apart CHEMICALLY. An example of a compound is water _______, and glucose___________ and table salt_______.
Mixture
A mixture is the addition of matter that is NOT chemically combined. Mixtures can be PHYSICALLY separated! Example: Salad, sand and iron, Kool-Aid in water, salt water, pen ink, sugar crystals in water.
Post-Lab Saltwater Lab 1. Sodium is in Group ____ and has _____valence electron. Chlorine is in Group ____ and has ____ valence electrons. Sodium and Chloride combines to form Sodium Chloride, also known as Table Salt. You can conclude that any Element from Group 1 can combine with any element in Group ____ to form an Ionic bond with _____ valence electrons, making it stable. 2. Beryllium is in Group ____ and has ____ valence electrons. Beryllium can form an Ionic bond with _______, which has six valence electrons. You can conclude that Beryllium, which is in Group ___ can combine with any element in Group____to form an ionic bond with _____ valence electrons to make the compound stable. 3. Groups 1 and 2 easily give away its outer electron(s). Doing so, makes the element more stable and more _____. It is known as a ca+ion. 4. Groups 17 and 18 can easily receive electron(s). Doing so will make the elements more ________. It will be known as a a(n)ion.

Lilian plans to go to Claire’s this Saturday at Baybrook Mall. She is looking for supplies to make a necklace. She purchases pink beads, super glue, white beads, and some string. Use Lilian’s supplies to make a great story that represents an element, a compound, and a mixture.
